Chapter 4: Q3. (page 136)

For the following figure, if $Δ A O D$ is isosceles right triangle with right $∠ A O D$ then the measure of $∠ A$ is __?

Short Answer

Expert verified

Then the measure is $∠ A ≅ ∠ D$ .

Step by step solution

Step 1. Check the figure.

Consider the figure.

Step 2. Apply the concept of isosceles triangle.

Property of isosceles triangle states that if two sides of a triangle are congruent, then the angles opposite to those sides are congruent.

Step 3. Step description.

From the figure $\bar{O A} = \bar{O D}$ .

Here the angle opposite to side $\bar{O A}$ is $∠ D$ and the angle opposite to side $\bar{O D}$ is $∠ A$ in $Δ A O D$ .

Since if the two sides of a triangle are congruent then the angles opposite to those sides are congruent then $∠ A ≅ ∠ D$ .

Therefore, the congruent angles are $∠ A ≅ ∠ D$ .
